25021-08-3, An elementary termolecular reaction involves the simultaneous collision of three atoms, molecules, or ions.25021-08-3, name is 2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetic acid. Here is a downstream synthesis route of the compound 25021-08-3
Trifluoroacetic Acid/1-[(2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetyl]piperidin-4-yl N-{(2S)-2-amino-4-[{(1R)-1-[1-benzyl-4-(2,5-difluorophenyl)-1H-pyrrol-2-yl]-2,2-dimethylpropyl}(glycoloyl)amino]butanoyl}-beta-alanyl-L-valyl-N5-carbamoyl-L-ornithinate (1:1) The synthesis was carried out by coupling of 25 mg (0.034 mmol) of Intermediate C61 and 29 mg (0.041 mmol) of Intermediate L69 in the presence of HATU and N,N-diisopropylethylamine, followed by hydrogenation with palladium on activated carbon (10%) under standard pressure, then coupling with (2,5-dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetic acid in the presence of HATU and N,N-diisopropylethylamine and finally removal of the 2-(trimethylsilyl)ethoxycarbonyl protective group with zinc chloride. HPLC purification gave 11 mg (26% of theory over 4 steps). LC-MS (Method 1): Rt=0.86 min; MS (ESIpos): m/z=1061 (M+H)+.
There are, however, a few established termolecular elementary reactions. The reaction of nitric oxide with oxygen appears to involve termolecular steps. you can also browse my other articles about 2-(2,5-Dioxo-2,5-dihydro-1H-pyrrol-1-yl)acetic acid
